Most lenders treat FIFO income differently to standard wages, and understanding what they actually look at can change your borrowing capacity by tens of thousands of dollars.
How Lenders Calculate Your FIFO Income
Lenders assess your income by averaging your last two years of earnings and applying a haircut to allowances that might not continue. Consider a mobile plant operator on a 2:1 roster earning a base salary of $90,000 plus $40,000 in allowances. Some lenders will only count 80% of the allowances, which reduces your assessed income from $130,000 to $122,000. That difference alone can reduce your borrowing capacity by around $40,000 to $50,000, depending on your other commitments. The lender wants proof that your allowances are ongoing, which means they'll look at whether they appear consistently across your payslips and tax returns. If your allowances vary significantly from month to month, expect them to average the lower end or discount them further.
This calculation matters because FIFO roles often package income differently to metro jobs. Your payslip might break down into base, site allowance, living away from home allowance, and overtime. Not all of those components carry the same weight with a lender. Base salary gets counted at 100%, but everything else depends on the lender's policy and how consistently it appears in your employment history.
What Documentation You'll Need to Provide
You'll need two years of tax returns, two years of PAYG summaries, your last three to six months of payslips, and a letter from your employer confirming your ongoing roster and allowances. Lenders want to see that your income is stable and that your contract isn't ending in six months. If you've been with your current employer for less than two years but you've been in the same industry and roster pattern, some lenders will accept that continuity. Others won't. The difference between a lender who counts your full history and one who resets the clock every time you switch employers can be significant when you're trying to apply for a home loan in a sector where contract turnover is normal.
If you've been contracting or moved between labour hire and direct employment, you'll also need to show that the work itself has been continuous, even if the employer name changed. Some lenders classify any switch from permanent to contract as a probationary period and won't lend until you've completed six to twelve months in the new structure.

Casual and Contract Roles
Casual and contract FIFO workers are treated as higher risk unless you can prove at least twelve months of continuous work in the same role. A diesel mechanic working through labour hire on a casual contract will need to show that their roster and income have been consistent across that period. If your hours fluctuate or your contract has been renewed multiple times with gaps, some lenders will decline the application outright. Others will lend but reduce the income they're willing to assess, which lowers what you can borrow. The lenders who do accept casual FIFO income often require two full years of tax returns showing the same work pattern, and they'll still apply a discount to your assessed income compared to someone on a permanent contract.
The practical outcome is that moving from permanent to casual employment, even if your actual take-home pay stays the same, can reduce your borrowing capacity or delay your application until you've built up enough history in the new arrangement.
Probation Periods and New Employment
Starting a new FIFO role usually means a three to six month probation period, and most lenders won't process your application until that period is finished. If you've moved from one FIFO employer to another in the same occupation and roster type, some lenders will accept your application immediately, while others will still want you to wait out probation. The distinction comes down to whether the lender views the role change as a career progression or a fresh start. A heavy diesel mechanic moving from one mine site to another on a similar roster will generally have fewer hurdles than someone moving from construction to mining, even if both are FIFO.
In a scenario where someone switches from a 2:1 roster to a 1:1 roster mid-application, the lender may reassess the income and borrowing capacity based on the new pattern, which can delay settlement if the figures no longer align with the purchase price.
Allowances That Lenders Discount or Exclude
Living away from home allowances are the most commonly discounted. If your payslip shows $1,500 per month as LAFHA, the lender might only count $1,200 of it, or exclude it entirely if it's structured as a reimbursement rather than income. Overtime is treated the same way unless you can demonstrate it's been consistent for at least twelve months. A truck driver earning $110,000 with $25,000 of that coming from overtime will see that overtime either fully counted, partially counted, or ignored, depending on the lender and how regular it's been. The difference affects whether you can borrow $450,000 or $520,000.
Bonus payments and site-specific loadings are typically excluded unless they've appeared in every pay cycle for two years. One-off retention bonuses or project completion payments won't count, even if they're substantial.
How Roster Patterns Affect Serviceability
Your roster pattern doesn't directly change your borrowing capacity, but it does affect how lenders view your job security. A 2:1 roster is seen as stable and typical for the industry. A 1:1 roster might be flagged as higher intensity, and some lenders will want additional confirmation from your employer that the arrangement is ongoing. If you're on a 3:1 or longer rotation, expect the lender to ask why, especially if that's not the standard for your occupation. The concern isn't the roster itself but whether it indicates a contractor role or short-term project work rather than permanent employment.
Serviceability calculations assume you're working year-round, so any unpaid leave or gaps between contracts will reduce your assessed income. If your tax return shows $120,000 but you only worked ten months of the year, the lender will notice and adjust accordingly.
Self-Employed FIFO Contractors
Self-employed contractors operating under their own ABN face different criteria entirely. You'll need two years of tax returns showing consistent income, and lenders will use your taxable income after deductions, not your gross. If you've claimed $30,000 in deductions to reduce your tax, that same $30,000 comes off what the lender will assess. A contractor earning $150,000 gross but showing $95,000 taxable income will be assessed on the lower figure. The solution for some contractors is a low doc loan, which uses alternative documentation like BAS statements or an accountant's letter, but these typically come with a higher interest rate and require a larger deposit.
If you've recently switched from PAYG employment to contracting, most lenders won't consider your application until you've completed two full financial years under the ABN, even if you're doing the same work for the same site.
Switching from FIFO to Local Employment
If you're planning to leave FIFO work after settlement, don't mention it in your application unless the lender specifically asks about your future employment intentions. Your loan is assessed on your current income, and lenders assume that income will continue. If you disclose that you're moving to a lower-paid local role in six months, the lender will assess you on the lower income, which might mean you no longer qualify for the loan amount you need. This comes up often with applicants who want to transition out of FIFO once they've purchased a home, but raising it too early in the process can kill the application.
If the role change happens after settlement, it's your responsibility to ensure you can still afford the repayments, but the lender won't reassess your income unless you're refinancing or applying for additional credit.
Income Verification for Investment Loans
The income assessment process is the same whether you're applying for an owner occupied home loan or an investment loan, but serviceability is calculated differently. Lenders apply a rental income discount, usually 80%, and they'll factor in the investment property's outgoings like strata, rates, and landlord insurance. Your FIFO income still needs to cover the gap between rental income and the loan repayments, plus your living expenses. If you're already servicing an owner-occupied loan and you're applying for an investment loan on top of it, your FIFO income will need to stretch further, and any discounted allowances will tighten your serviceability faster.
We regularly see applicants who can afford both loans in practice but fall short on the lender's serviceability test because their allowances are heavily discounted or their overtime isn't being counted.
If your income structure has changed in the last two years, if you've switched from permanent to contract, or if your allowances make up more than 30% of your total pay, call one of our team or book an appointment at a time that works for you.

Frequently Asked Questions
Do lenders count all of my FIFO allowances when calculating borrowing capacity?
No, most lenders discount allowances to between 80% and 100% depending on how consistently they appear across your payslips and tax returns. Base salary is always counted in full, but living away from home allowances, overtime, and site loadings are often reduced or excluded entirely.
How long do I need to be in a FIFO role before I can apply for a home loan?
Most lenders require you to complete any probation period, typically three to six months. If you've moved between FIFO employers in the same occupation and roster type, some lenders will accept your application immediately, while others still want proof of ongoing employment.
What documents do I need to provide as a FIFO worker applying for a home loan?
You'll need two years of tax returns, two years of PAYG summaries, your last three to six months of payslips, and a letter from your employer confirming your ongoing roster and allowances. If you're contracting, you may also need to show continuous work history even if the employer name changed.
Can I get a home loan as a casual FIFO worker?
Yes, but you'll need at least twelve months of continuous work in the same role, and most lenders require two full years of tax returns showing consistent income. Casual FIFO income is often discounted compared to permanent employment, which reduces your borrowing capacity.
How do lenders assess self-employed FIFO contractors?
Self-employed contractors need two years of tax returns, and lenders assess your taxable income after deductions, not your gross income. If you've recently switched from PAYG to contracting, most lenders won't consider your application until you've completed two full financial years under your ABN.
